'DUsir-ARREsQf-i'lia FOR HOT-AIR PIPEs.

SPECIFIQCATIONHforming part of Letters Patent No. 7185591, dated January 13, 1903. l AppliuationilledAugngt,1902s Serial No. 120.940. (No model.) y A To all whom it may concern:

' Be it known that I, LAURA D. YOUNG, a citizen of the United States, residing at Akron, in the county of Summit and Statevof Ohio, have invented a certain newfand useful Improvement inv Dust-'.Arresters for Hot- Airv Pipes, of which the'following is a complete specification. A

lMy invention has relation to improvements in devices for cleansing v the air passing through the hot-air pipes from the furnace to .theregisterby removing therefrom particles ofdustand soot held in suspension therein j and that would otherwise pass into the apartment to be'heated and deposited on the walls -and'furnitu re.

y hot air will enter the apartment wholly freed withdust and soot. l

To theaccomplishmentof the aforesaid ob- `therefrom; and a further object is to provide a n umber of cleansing-layers in the same appliance; anda final object islto so construct the appliance ,that these layers may be removed from time to time as they v become charged jects my invention consists in 'the peculiar and novel construction, arrangement, and

'combination of parts hereinafter described andthenfspeci iically pointed out in the claim,

reference being' had to l the` accompanying drawings, which form apart hereof. u

4In the accompanying drawings, .in which similar reference-numerals.indicate like'parts in the different'viewsFiguvre`1 is a plan'of my linvention, ad'FigfZa section` of the same .at the'line ma: of Fig. 1.

Referring to the figures, 1 is a I n presence of.-

lshort cylindrical cause having at its upper enda iiange 2, adapted to" rest lon the end of the hot-air induction-pipe. vExtending across this ,case

1 are diaph-ragms 8 9, of coarse'wiremetting, slightly separated from oneanother. Telescopicallytt'ing the ends-of this i case `l at either endare circular rims 3 4, having anges 5,6jto arrest` their completee'ntrance into the cylinder 1, but so close fitting as to be retained byfriction. Across the rims 3 4 are secured 5o ldiaphragms of coarsewire-netting 8, re-

spectiveiy, and the spaces between the diaphragms'7 8 and 9 10 are loosely filled with lighttluffy layers of asbestos in Iieecy condition.4` This ieecy mass of asbestos, which is incombustible, aiords a free progress for the heated air, whileat the same time it consti- .tutes an eiective resistance toany articles held in suspension, thereby co'nstitutinga practical strainer'for the air.

A Although only two diaphragmsof asbestos wool are-shown, it is manifest that their number may be increased without departing from my invention, which is-'-v An improved hot-airA cleanser for furnacepipes which consists of an inclosing case, diaphragms extendingacross saidcaseand separated from each other, made upv of coarse wire-netting, telescoping rings adapted to enter either end'of said case each provided with va diaphragm of wire-netting and a stratum of .Iiutfy asbestos between the diaphragme in thel rims and the diaphragms in the case.

In testimony that I claim the above I herel-unto set iny hand in thepresen'ce of twosnb'- scribingwitnesses. x
